FI'RE -EXTINGUISHING APPARATUS.

SPECIFICATION forming part Of Letters Patent No. 260,641, dated July I, 1882. Application filed September 12, 1881. (No model.)

To all whom it may concern Be it known that I, JOHN W. BIsuoP, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Fire-Extinguishing Apparatus; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, 1n-=- Figure 1, a view showing the apparatus as arranged in a building; Fig. 2, the chain connection enlarged; Fig. 3, a side view of the distributer; Fig. 4, a'longitudinal section of the distributor; Fig. 5, an end view of the distributer.

This invention relates to an improvement in fire-extinguishing apparatus, with special reference to that class of such apparatus in which pipes are arranged through a building or rooms therein, with distributors at intervals in the pipes provided with fusible plug or equivalent devices, which,when the heat in the room shall have risen to a certain temperature because of. fire therein, will be released and the water lib-, erated to be forced through the distributer in the form of spray to extinguish the fire which caused the heat.

In the use of this class of apparatus it is usually necessary that a constant head or force of water shall be in the pipes, so that when liberated it will be discharged with great force. Such constantflow of water has heretofore been produced by a reservoirfeither in the form of tanks in the building or from water-works.

In places where there are not permanent water-works, tanks are necessarily employed. These require constant watching in order to secure a supply, and are subject, to a greater or less extent, to leakage and consequent damage to property, so that tanks are almost as dangerous to property as the fire which they are intended to aid in extinguishing.

The object of-this invention is to dispense with water works or tanks and adapt the apparatus to large manut'actories, where power is readily attained, by means of which the supply of water may be forced into the pipes whenever and wherever it fire shall occur; and the 'distributers at the point where the said fire occurs, as more fully hereinafter described.

In illustrating my invention I show it as employing water-power, in which A represents the water wheel or motor receiving water through a pipe, B, from the fluine C,in theusual manner for turbine and like wheels;

D represents a rotary pump connected by gearing to the wheel-shaft, so that the revolution of the wheel imparts corresponding motion to the pump, which will draw water from the supply'through a pipe, E, and discharge it into the pipe F, which leads to the different parts of the building, provided at different points with distributors to, in the usual manner for this class of fire-extinguishers.

The supply of water'to the wheel-through the pipe'B is cut oft by a gate or valve, b, and which valve is to be automatically opened whenever a fire occurs. As a suitable device for operating thisvalve,Iherereprcsentaflexiblediaphragm, d, in a chamber, 0, to which water is admitted beneath the diaphragm through atube,f. This diaphragm is provided with a spindle, g, which engages a lever, h, one end hung upon a fulcrum, t', the other connected to an arm, is, on thevalve b, so that when water is admitted into the chamber 0 below the-diaphragm it will force the diaphragm to rise. The movement of the diaphragm, communicated to. the lever h through the spindle g, turns the Valve 1) in the pipe B, so as to permit the water to flow to the wheel.

1n the pipefis a valve, l, operated by a lever, m. From this lever a wire, chain, cord, or other equivalent device, a, extendsthrough the building to the points to be protected, and at those points-say near the distributers-fusible connections 7' are made. This connection is best done by means of a chain. (Seen enlarged in Fig.2.) Two links,s s,in the chain,a little distance from each other, are brought together and soldered, leaving the intermediate is not new; but I am not aware that a tubular distributer having openings on its side extending over onto its outer end has been provided with a sleeve, whereby not only the capacity of the opening in the side of the distributer may be varied, but the sleeve may be thrownforward to'project beyond the end of the distributer, and thereby contract the discharge into a stream.

I claim-- 1. In a fire-extinguishingapparatus, the combination of the following elements: first, a

pump to receive the water and force it to the ments: first, a pump to receive water and force it to the distributers; second, a water-motor in connection with said pump, and a gate or valve in the supply to the motor; third, mechanism, in connection with said gate, arranged to be operated by an inflow of water to open the gate to the motor; fourth, a valve in the pipe leading to said gate-operatingmechanism, connected-by fusible connections at points or parts of thebuilding to be protected, and so that when said connections are broken the valve will be opened and permit the flow of water to the gate-opening mechanism, substantially as described.

3. In a fire-extinguisher, the distributer constructed of tubular shape, with projecting hollow rim at its outer end, and with spiral slots or openings on the side of the tube, extending through the said rim to the recessed center, substantially as described.

4. In a fire-extinguisher, a distributer constructed of tubular shape, with slots or openings on. the side of the tube, extending over onto the outer end of the distributer, combined with a sleeve, R, adjustable on said sleeve to vary extent of opening and contract the water into a stream, substantially as described.
